LIGHT DEFLECTOR.

Application sied April 5,

My present invention has reterence to an attachment for headlamps for automobiles or like vehicles, and is designed to provide a means whereby the light rays from such lamps will be directed downwardly onto thel road surface and out oi' the path of vision ot an approaching automobile or pedestrian and whereby accidents resulting` from the dazsling lights o1 automobiles will be etl'ectively prevented. l

A further object is the provision oit an attachment for this purpose which shall be of a simple construction, cheaply manufactured and readily attached to and removed trom any ordinary construction of automobile headlamps.

A further object is the provision ot an attachment for this purpose which shall be etl'ectively clamped in the headlamp and which also attords an effective support for the lens ot the headlamp.

To the attainment ot the foregoing and other objects which will present themselves, the improvement also resides in certain other novel features ot construction., combination and operative association ot parts2 one satist'actory embodiment of which is disclosed by the accompanying drawings.

ln the drawings:

Figure 1 is a front elevation ot a headlamp equipped with the improvement.

Figure 2 is a sectional View approximately on the line 2 2 of Figure 1.

Figure 3 is a sectional view approximately on the line 3-3 o1 Figure 2 l Figure 4l is a perspective view ot one ot the clamps detached :from the rim oit the headlamp.

Figure 5 is an enlarged detail sectional View approximately on the line 5--5 or Figure 3.

1n the drawings, the numeral 1 designates the body ot an ordinary headlamp for automobiles and 2 the reflector t ierein and 3 the bulb which has its base received through the reflector. The rim for the headlamp is indicated by the numeral 1 and is ot the ordinary construction, the same being provided with the usual bayonet slots7 (not shown) to engage with the lugs on the lamp housing' 2 (also not shown). The rim l is provided with the usual peripheral rounded portion or bead 5 and to this bead I secure at spaced intervals either by soldering', riveting or the like. the curved ends 5" ofthe clamps 6 oit the improvement. Each clamp 6 is bent uponV 1928. Serial No. 267,643.

`outer periphery channeled or its opposite tacos formed with outstandingl ilanges 12, respectively. The outer flange is designed to conta-ct with a compressiblegasket 13 that is arranged against the inner face of the lens 8,

and the inner tace of the flange 12 is designed to be contacted by a headed that is screwed through the ears 9.

The ring member' has its flange portion 12 provided with equidistantly spaced notches 15 arranged in a line with the bayonet slots in the rim and with the lugs on the lamp housing. These notches are designed to receive the clamps 6 therethrough after the improvement has been attached, through the medium olii the bolts 14:, to the lens 8 and the rim 1, the rim, lens and my improved light detlector being then turned to bring the lugs on the lamp housing into the otset passages ot' the baycnet slots. l

Arranged transversely between the inner sides of the ring` 11 there are preferably equidistai'ltly spaced downwardly inclined shutters 1G. These sluittel's maybe oit translucent dass or may be o1l an unbreakable matebolt member 14 the openings 1() in l?) rial, suitably colored to prevent the direct rays ot' light passing' therethrough. When the device attached in a manner as just describl-id, the shutters 16 will be arranged transversely with respect to the lainphousinfr or in the positions illustrated in Figures 1, 2, 3 and 5 ot the drawings. Vhen soarranged it will be noted that the rays of lig-ht will pass between the shutters and may be directed downwardly onto the road. The lower edge orI one o1 the shutters is approximately in a line with the upper edge ot the next shutter so that straight rays ot' light cannot be directed between the shutters.

The construction of my improvement and the advantages thereof will, it is thought, be understood without further detailed description but obviously I do not wish to be restricted to the precise structure herein shown and described and, therefore, hold myself `mobi1e or the like, having a detachable rim Y for holding the lens inthe lamp housing, a peripherally grooved and notched lshutter carrying ring lat the inner face of the lens, and

-a compressible gasket between the ring and lens, spaced clamps each having one of its ends fixed on the Vrim and integrally provided with depending lugs'to contact Vwith the periphery of the lens, and having their outer ends downturncd to provide ears to be received through the notches in the grooved ring and to permit of the said grooved ringr being turned to bring its notches out of register with the ears and bolt members screwed through the ears and contactingr with the inner face of the ring to compress the latter against the gasket and the lens against the rim.

In testimony whereof I aix my signature.

ANTHONY J. MARA.
